Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic surface cleaning, and in particular to a device for cleaning the surface of a building photovoltaic assembly. Background Art

[0002] Clean energy is gradually replacing energy generated by traditional thermal power generation, reducing the emission of carbon dioxide, sulfide and various harmful substances. Among them, the most widely used clean energy is photovoltaic devices, which use sunlight to generate electricity. No harmful substances are produced in the whole process. In order to ensure that photovoltaic equipment can better receive sunlight, photovoltaic modules will be cleaned regularly to ensure the normal operation of photovoltaic modules.

[0003] In the prior art, for example, the patent document with the announcement number CN117938064B discloses a photovoltaic panel erection mechanism on the top of a building, and also discloses a technical solution that can simultaneously perform a secondary brushing and cleaning treatment on the surface of the photovoltaic panel by setting a cleaning mechanism and a liquid spraying mechanism.

[0004] However, in actual application, in order to improve the solar energy utilization rate of building photovoltaic components, it is usually necessary to splice several groups of photovoltaic panels into a row. The number is large. Therefore, if a set of cleaning mechanisms and spray mechanisms are independently set on each group of photovoltaic panels, it will not only increase the cost, but also make it difficult to splice the photovoltaic panels. The length of the spliced ​​photovoltaic panels is too large, which takes up a lot of space. At the same time, the dust and impurities cleaned from each group of photovoltaic panels are difficult to collect uniformly, and the dust and impurities still need to be cleaned manually.

[0005] For example, the patent document with announcement number CN219436944U discloses a solar photovoltaic panel cleaning device, which also discloses a mounting bracket and a walking assembly, wherein the walking assembly includes a walking frame fixedly connected to the frame body; it can be seen that the cleaning assembly and the walking assembly in the prior art are fixed and inseparable from the photovoltaic panel bracket, so during production, each set of photovoltaic panel brackets needs to produce a corresponding set of cleaning assembly and walking assembly, which not only increases the production cost, but also because both are fixed to the photovoltaic panel bracket, when damage occurs, it is difficult to disassemble and repair.

[0006] For example, the patent document with announcement number CN115473486A discloses a photovoltaic panel with self-cleaning function for photovoltaic power generation and its use method, and also discloses a movable frame and a scraper, wherein the scraper is fixed on the movable frame. Although this group of scrapers can clean the photovoltaic panel, it is only suitable for cleaning a single photovoltaic panel. When multiple groups of photovoltaic panels are spliced, there is a photovoltaic panel support frame between two adjacent groups of photovoltaic panels, and the existing scraper is fixedly installed and cannot be raised or lowered, so the support frame will interfere with the movement of the scraper, which is difficult to meet the actual application needs. Summary of the invention

[0007] The purpose of the present invention is to provide a building photovoltaic module surface cleaning device to solve the following technical problems:

[0008] 1) It is impossible to clean the spliced ​​photovoltaic panels in one go;

[0009] 2) The dust and impurities cleaned from each group of photovoltaic panels cannot be collected uniformly and need to be cleaned twice;

[0010] 3) The existing cleaning components and walking components are fixed and inseparable from the photovoltaic panel bracket, which increases the production cost and is not convenient for maintenance;

[0032] (4) The shovel in the present invention scoops up the impurities and temporarily stores them in the storage tank. Since the photovoltaic module is in an inclined state, the impurities in the storage tank will gather on the side close to the movable plate. When the shovel moves to the end of the photovoltaic module and separates from the photovoltaic panel, the movable plate is pushed by the pushing part to slide in the direction away from the conical plate, so that the impurities in the storage tank can be discharged under the action of gravity. Similarly, the cleaning staff only needs to place a trash can at this location to collect the impurities. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that the first positioning plate 301 is installed at a high position of the photovoltaic module 1, and the second positioning plate 310 is installed at a low position of the photovoltaic module 1. The first positioning plate 301 and the second positioning plate 310 are driven to move toward each other by the adjustment module, so that the support frame 103 can be embedded in the positioning groove 307, and then the first positioning plate 301 and the second positioning plate 310 can be fixed on the photovoltaic module 1.

[0057] See also Figure 3-Figure 6 The water delivery module includes a water delivery pipe 402 connected to the spray pipe 4, the other end of the water delivery pipe 402 is connected to the water pump 403, and the other end of the water pump 403 is connected to the water source through the water inlet pipe 404; it can be explained that during the cleaning process, the water pump 403 is started, the water pump 403 draws the cleaning water from the water source through the water inlet pipe 404 and then transports it to the spray pipes 4 on both sides through the water delivery pipe 402.

[0058] See also Figure 3-Figure 6 In order to effectively remove the stubborn stains attached to the surface of the photovoltaic panel 101, a shovel plate 5 is provided on the side of each group of spray pipes 4 away from the cleaning roller 202. The shovel plate 5 slides and fits with the surface of the photovoltaic panel 101, and a conical plate 501 is provided on the end of the shovel plate 5 away from the spray pipe 4; specifically, during the cleaning process, the cleaning module 2 first scrapes off the stubborn stains attached to the photovoltaic panel 101 through the conical plate 501 at the end of the shovel plate 5, thereby facilitating the subsequent spraying and cleaning of the photovoltaic panel 101.

[0059] In order to collect the impurities after shoveling, in this embodiment, refer to Figure 3-Figure 4The end of the shovel plate 5 away from the conical plate 501 is fixedly provided with a baffle plate 503 perpendicularly, the end of the baffle plate 503 close to the first positioning plate 301 is fixedly provided with a closing plate 502, and the end close to the second positioning plate 310 is fixedly provided with a movable plate 504. The shovel plate 5, the baffle plate 503, the closing plate 502 and the movable plate 504 are enclosed to form a storage tank for storing impurities, wherein the baffle plate 503 is provided with a pushing part, and the pushing part is used to drive the movable plate 504 to move in a direction away from or close to the conical plate 501; specifically, the present invention The shovel plate 5 in the embodiment scoops up the impurities and temporarily stores them in the storage tank. Since the photovoltaic module 1 is in an inclined state, the impurities in the storage tank will gather on the side close to the movable plate 504. When the shovel plate 5 moves to the end of the photovoltaic module 1 and separates from the photovoltaic panel 101, the movable plate 504 is pushed by the pushing part to slide in the direction away from the conical plate 501, so that the impurities in the storage tank can be discharged under the action of gravity. Similarly, the cleaning staff only needs to place a trash can at this position to collect the impurities.

[0060] In this embodiment, please refer to Figure 1 and Figure 4 The pushing part includes an L-shaped bracket 506 fixedly arranged on the baffle 503, a first guide rod 507 fixedly arranged on the L-shaped bracket 506, a movable seat 509 slidably arranged on the first guide rod 507, a positioning seat 510 fixedly arranged on the movable plate 504, the movable seat 509 is fixed to the positioning seat 510, a first spring 508 is arranged on the first guide rod 507, one end of the first spring 508 is fixed to the movable seat 509, and the other end is fixed to the L-shaped bracket 506, wherein the two ends of the second positioning plate 310 are respectively A pushing frame 505 is separately fixedly arranged; it can be explained that when the shovel board 5 moves to the end of the photovoltaic module 1, the positioning seat 510 abuts against the pushing frame 505, and as the shovel board 5 continues to move, based on the limiting effect of the pushing frame 505, the positioning seat 510 and the movable plate 504 stop moving, and the positioning seat 510 synchronously drives the movable seat 509 to slide on the first guide rod 507 to compress the first spring 508. When the shovel board 5 moves in the opposite direction, the movable plate 504 can be driven to reset through the first spring 508.

[0061] For each set of photovoltaic panels 101, the thickness of the supporting frame 103 around it is greater than the thickness of the photovoltaic panel 101 body. Therefore, when the shovel 5 moves along the surface of the photovoltaic panel 101 to the position of the supporting frame 103, the supporting frame 103 will interfere with the shovel 5 (see Fig.10 ), as a further solution of this embodiment, please refer to Figure 6 and Figure 8A wedge-shaped seat 6 is provided between the baffle plate 503 and the spray pipe 4, and the wedge-shaped seat 6 is fixed to the cleaning plate 201 through a positioning rod 604. An inclined guide surface 601 is provided on the side of the wedge-shaped seat 6 close to the baffle plate 503, and a limiting plate 603 is fixedly arranged on the side of the baffle plate 503 facing the spray pipe 4. A guide wheel 602 that rolls and abuts against the inclined guide surface 601 is rotatably arranged at the end of the limiting plate 603.
